Abstract:
|
In the sheet metal incremental forming,the orientation of bolster model positioned by guide pin is inefficient and rough because of the floating of bolster model and fit tolerance between guide pin and aligning hole.Auto orientation system based on machine vision obtains the coordination of aligning holes after the digital images have been captured and processed.Then,CNC system makes off-line transformation of machine coordinates to realize the adaptation of position and attitude from forming trajectory coordinates to bolster model coordinates.This non-touch agile locating system is rapid and precise.
